Research On MSW Incineration And Power Generation

With the development of urbanization, the amount of MSW in China is increasing continuously and 200 cities have run into a condition being surrounded by waste. Aiming at choosing incineration equipments which have the virtue of advanced technologies, super performance, guaranteed quality, reliable running, reasonable cost and friend to environment, it is discussed in this study to research design schemes of waste incineration plant in medium scale and small scale, meeting the need of medium and small cities in our country, on the purpose of waste harmless, minimization and recycling, stating the key points on the complete technical papers, systematic research content and practical design schemes . The paper can also be taken as an important reference of construction preparation of waste incineration plants.The amount and composition of MSW in China are both changing continuously: the amount of MSW takes a ascend trend by 7-9% per year and the composition of sludge is "low heating value, high water content and varied". However, in some developed cities, the heating value of refuse has surpassed 1000kC/kg, turning refuse incineration into possibility.This paper introduces the processes and equipments utilized widely in refuse incineration in China and abroad. Combined with the situation of China and real project examples, it is suggested to select flowing-bed incinerators under the condition of adopting the way of waste disposal industrialization or select mechanical-grate incinerators under the condition of adopting the way of waste treatment in commonweal.In view of characteristics of powders, harmful gas (especial for Dioxins), wastewater and noises generated in the incineration process, some measures is proposed combined with real projects. In addition, each process system is described in detain related with real projects and the project location and covering area indexes are analyzed simultaneously, put forward some detailed advice in project design.Based on the detained research of economic profits of waste incineration and power generation, it is indicated that the cost of waste incineration is far lower than that of sanitary landfill. With the continuous exploitation and application of waste incineration technologies in China, the industrialized waste incineration plants, which generate power and provide heat through waste incineration, is becoming more and more. Waste incineration and power generation not only possesses social benefits and environmental benefits, but also has excellent economic benefits by reclaiming the energy in refuse, achieving the aim of changing waste into resource,.
